Maritime accidents caused by a ship include collisions, sinking, stranding and fire etc. This study is intending to consider fire accidents among such diverse marine accidents. It is much likely that various sorts of fires break out because crews are living in a narrow space for long periods of time consequent on the ship's characteristic of sailing on the sea. This study carried out a simulation through the special program for fire analysis - FDS (Fire Dynamics Simulator) in order to find the effective evacuation time, i.e. life survival time. Particularly, this study did comparative analysis of the influence on the survival of cadets based on the collected simulation data by fire size and sort. As a result of the analysis, It was analyzed the Evacuation Allowable Limit Temperature $60^{\circ}C$ and resulted that there is no influence in evacuation by temperature. In case of visibility analysis, it reached to 5m which is the Evacuation Allowable Limit at 117 seconds under the condition of wood fire in 1MW. When there is Kerosene in 1MW, it took 92.4 seconds to reach by 5m which is the Evacuation Allowable Limit. Theoretical evacuation time for the non-tilted ship was 118.8 seconds in 1MW sized fire so it is shown that the most passengers are met the evacuation safety in case of wood fire. However, the majority of passengers could not be ensured the evacuation safety in Kerosene case.

It is naturally to be expected that the stress of seafarers has some specific characters compared to other workers who are labouring on land. Because the physical rigors of working and living at sea has been endured as a part of job. The excessive stress caused by shipboard life, their jobs, can weaken the health status and court the work related accidents. Also it will be the immediate causes of marine accidents such as collision, sinking etc. In this paper, a questionnaire survey was undertaken to find out the approximate quantity and source of seafarer's occupational stress. And the heart rate of deck officers on duty was measured to develop a profile of correlation between the stress and the work.

The ocean is the largest reservoir of carbon in the climate system. Atmospheric $CO_2$ is efficiently transferred to the deep ocean by a process called the biological carbon pump: photosynthetic fixation of $CO_2$ at the sea surface and remineralization of sinking organic carbon at depths are main causes for the vertical contrast of carbon in the ocean. The sequestered carbon to the deep ocean returns to the sea surface by ocean circulation. Part of the upwelled $CO_2$ leaks into the atmosphere through air-sea gas exchange. It has been suggested that the air-sea partitioning of carbon has varied in concert with the glacial-interglacial climate variations, due partly to changes in ocean circulation. In this review paper, we briefly summarize key concepts of the oceanic carbon pump. We also discuss the response of the air-sea carbon partitioning to change in ocean circulation in the context of the glacial-interglacial climate change.

Mokpo city is a coastal city located at the south western coast of the Korean Peninsula. Large regions within Mokpo are subjected to significant subsidence because about $70\%$ of the city area is a reclaimed land from the sea. Although no confidential quantitative measurements are available up to the present, the subsidence rate is as much as several cm per year. In this study, we aimed to estimate the subsidence rate over Mokpo city by using twenty-six JERS-1 SAR dataset from September 1992 to October 1998. Several tens of differential interferograms were processed from JERS-1 dataset and STRM 3-arc DEM. The results indicate continuous subsidence in Dongmyung-dong, Hadang-dong and Wonsan-dong in city, and the subsidence velocity reach over 4 cm/yr in the most highly sinking area. For facilitating the analysis of time-varying surface change, we also carried out an interferometric SAR time series analysis using permanent scatterer and consequently determined space-time maps of surface deformation at each acquisition time of JERS- 1 SAR.

"The Golden Mirror of Medicine(醫宗金鑑)" was compiled by the medical officers of the Qing government, headed by Wu-Qian(吳謙)."The Elimination &Supplement about the Famous Prescription Comments(刪補名醫方論)", a collection of notes written by famous scholars, is one part of "The Golden Mirror of Medicine(醫宗金鑑)" . Through the translation and comparative study of invigorative prescription(補氣方劑) in "The Elimination & Supplement about the Famous Prescription Comments(刪補名醫方論)" of "The Golden Mirror of Medicine(醫宗金鑑)" with "The Famous Prescription Comments on Ancient and Modem Times(古今名醫方論)" , we confirmed that many sentences of "The Famous Prescription Comments on Ancient and Modern Times(古今名醫方論)" were quoted, but that most of the text was not quoted as the same: it was revised and supplemented. In organization, invigoration prescriptions are placed at the head of the chapter, indicating their importance. In classification, prescriptions for reinforcing middle-jiao(中焦) and replenishing qi(補中益氣湯類 方劑) were usually included in the invigoration prescriptions(補氣方劑), which is explained in chapter II, thereby clearly distinguishing between treatments of deficiency of qi(氣虛) and combining it with the sinking of qi of middle-jiao(中氣下陷).

The purpose of this article is to examine maritime accident and corporate criminal liability in comparison with cases and laws in UK and US. In Anglo-American law, a corporation can be convicted of and sentenced for a criminal offence. However, some theoretical difficulties lie in fixing a corporation with the appropriate mens rea. The Corporate Manslaughter and Corporate Homicide Act 2007 in England is to solve those difficulties and punish a corporation like a natural person. Comparing to Anglo-American law, a corporation is difficult to be punished in Korean law because it is a well recognized theory that only natural person is capable of committing a crime. However, safety in society and workplace is earning great concern in Korea, and emphasis is put on responsibilities of corporations. This article discusses the need for legislation on corporate manslaughter act in Korea with regard to the sinking of the MV Sewol.

In the west coast, south coast, and river basin, the use of geotextile mats has been increasing to improve the soft ground for making industrial facilities space and farmland. As an initial step to improve the vast and soft ground, the geotextile mats are laid and bonded to increase the bearing capacity of the wide ground for supporting construction equipment. Seam strength of geotextile mats exert a force only about 50% of the tensile strength of the fabric, which causes problems such as uplift and sinking in the soft ground. In this study, various types of geosynthetic matting techniques were investigated and the tensile strength of each method was compared and analyzed. Numerical analysis shows that stress increment in the ground due to the overburden load decreases when the seam strength of the geosynthetics mats is increased. When the seam strength was increased to 60, 70 and 80%, the bearing capacity of ground by geotextile mat was increased.

The sinking of the Sewol ferry has not only induced an intense conflict in Korean society but also been developed into a sociopolitical issue. This paper divides this accident into five stages and examines the records produced at each stage. The Sewolho Citizen Archive Network and the Ansan Citizen Record Committee began the archiving of Sewol and created the 416 Archives. The records of Sewol are social and political records that hold envidencial and historical value. They can be used to rebuild and recover the wounded community as well as to investigate the truth behind the case. Accident archiving collects materials different to the ones which public archiving does, allowing people to view the incident from a different standpoint. It is also characterized as an archiving of the current issue, social movement and regional community. Accident archiving is a method which ensures credibility and impartiality in memory. In light of Sewol archives, accident archiving can contribute to form mature democracy.
